How does stainless steel take away garlic smell on skin?

I read somewhere--and recently tried it, and it works. If you have garlic smell on your hands rubbing your hands/fingers on stainless steel will remove it. Just curious how. Thanks!|||Metal oxides create a breakdown of oil in your skin. When touching objects made of iron, perspiration from skin causes the iron atoms to gain two electrons. The doubly negative iron atoms react with oil in the skin, causing them to decompose, forming 1-octen-2-one.
